The LUXEON LED Fog Lamp is an OEM-grade fog lamp housing that utilizes
LED technology. It is for select vehicles only, as it replaces the
entire factory fog lamp housing. Unlike competing "LED fog lamps" these
actually are among the brightest possible LED fog lamp options.

With the newest projector optics, the light is directed perfectly at a
very wide angle, with a clear cutoff line. These lamps have been tested
for SAE compliance, and are DOT and ECE compliant.

The design features projector optics, directing light from genuine
Philips Luxeon T LEDs, binned at a 5000K pure white color. With a
constant current drive circuit, built-in passive heatsinking, and input
power smoothing, the fog lights will work perfectly for years.

The entire housing is weather-sealed, and features a GORE patch to allow
for depressurization of the housing when the light heats up and cools
down. These design characteristics are all similar to the quality and
thought that goes into OEM headlamps, which is why we are proud to call
these "OEM grade."

Please be aware: there are already many knockoffs of this design on the
market. Like any good knockoff, they appear the same, but they always
use thinner materials, poor sealing, lower-quality drive circuits, and
most noticeably, low-quality offbrand LEDs. Diode Dynamics only uses
genuine components in our products, with everything fully tested, to
ensure you will receive the highest performance possible.

Lumens: BUYER
BEWARE! Most sellers just provide "calculated" lumen numbers, based on
the maximum potential brightness of the LED chips on the bulb. For
example, if a bulb has five 10-lumen chips, they will rate it at 50
lumens. However, this is not accurate, as the design of an LED bulb does
not get rid of heat fast enough to run the LEDs at maximum.

These "calculated" lumen ratings are much, much higher than the true,
measured light output, so it will look like competitors' bulbs are
brighter than ours. This is because Diode Dynamics does not provide
inflated "calculated" numbers; we believe it is misleading. We test the
actual brightness of the bulbs in our lab, to provide real lumen output
measurements. Our measurements are accurate, but they are usually much
lower than the misleading "calculated" figures. Please click

Components. Diode Dynamics uses only the highest quality LED
chips in the production of its bulbs. This means we use only brand-name
suppliers such as Epistar, Cree, Osram, and Samsung.

While our bulbs may look the same as others on the market, most copycat
bulbs use economy-grade LED chips in order to reduce costs. This greatly
reduces the reliability and overall brightness of the bulb when you
compare it to Diode Dynamics.

Construction. Although LED technology allows for extremely long
bulb life, the market is flooded with cheap LED bulbs that fail
prematurely due to inferior construction. The worst enemy of LEDs is
excessive heat, and when bulbs are not designed properly, they do not
disperse heat as well, leading to premature failure.

Off-brand, cheap bulbs exhibit poor solder uniformity, high levels of
flux in the solder, uneven chip placement, low-gauge terminal wires,
poor assembly, and bulbs held together with inferior adhesives. At best,
solder joints will crack and fail on low-quality LEDs after a few weeks
of use. In the worst case, these bulbs can damage housings as the extra
flux and adhesive evaporates and creates a residue on the lens of the
housing.

Diode Dynamics bulbs are produced with modern, computerized equipment,
and only the best materials, to ensure complete uniformity, high
quality, and long bulb life.
